fuel trim troubles I have a 00 Silverado Z71 w/ 5.3L I can not get the fuel trims to go to zero or negative. The closest I get to zero is about +5. In the VE table I have some numbers in the 95+ range which would mean it is close to 100% efficient which is pretty much impossible. Any help or suggestions are welcome.
